MACHINE FOR DYEING.

SPECIFICATION forming part of Letters Patent No. 668,694, dated February26, 1901.

.Application iil'ed October 18, 1900. Serial No. 33,465. (No model.)

T @ZZ whom, it may concern:

Be it known that I, JOSEPH STEENBERGHE, asubject of the King of Belgium,residing at No. 6l Rue Piers, Molenbeek, near Brussels, in the Kingdomof Belgium, have invented a new and useful Machine for Dyeing andWringing Yarn, of which the following is a specification. f

The machine for dyeing hanks of yarn which forms the object of thepresent application for Letters Patent is devised especially for thedyeing of cotton yarn in indigo-vats, and it admits of the practicalrealization of this delicate operation, which has hitherto alwaysnecessitated very skilled dyers whose hands were repeatedly attackedbythe dye liquid.

The industrial use of this machine, which can be operated by any workmanand which gives a color of any desired shade and abso-A lutely uniformfor all the hanks of yarn operated upon, constitutes an improved stepforward and eects a very considerable economy in labor. i

In order better to set forth the advantages of the new invention in allrespects, it should be remembered that the operation by hand in theindigo-dye vats involves a certain number of operations or successivedyeings, according to the shade required, each of these immersione beingeffected in a different bath and involving a dipping followed by awringing,then a pressing and stretching of the yarn.

According to my improved system the machine is mounted upon a travelingframe above a series of vats containing the graduated baths. The machineeffects the dipping and then expresses the excess of the dye absorbed bythe yarn by squeezing the same without twisting it and withoutdisturbing the threads, so that the subsequent pressing or straining ofthe said yarn is no longer requisite.

My apparatus includes the following essential parts, namely: first, adipping-roller rotated above the bath and arranged to pass through thehank of yarn to be dipped; second, a stretching-roller also passingthrough the yarn and capable of being moved away from the dipping-rollerfor the purpose of stretching the said yarn out of the bath and -for thedifferent baths.

above the vat, and, third, a compression-roller which can be caused toapproach the dipping-roller for the purpose of squeezing the yarnbetween these two rollers, so as to eX- press the excess of dye takenup.

In order to make my invention more clear, I have illustrated the same inthe accompanvinfT drawings in which is re resented b way of example amachine according to my system.

In the drawings, Figure l shows a longitudinal elevation of the machinecapable of traveling above the dye-vats. The mechanism thereof isrepresented in the position of dipping. Fig. 2 shows a plan view of thesame apparatus and partly of its driving-gear. Fig. 3 illustrates anelevation, partly in vertical transverse seetion and upon a reducedscale, in order to show the general arrangement of the machine aboveeach dye-vat.

The mechanism is operated upon a horizontal frame or carriage formed ofthe longitudinal beams l, united by cross-bars and capable of travelingabove the dye-vats upon the little wheels 2 on the rails 3, secu redalong the lateral edges 4 of a vat 5, divided into as many compartmentsor vats as are requisite Upon the two longitudinal beams which supportthe machine proper are bolted two iron frames lla. and 1lb, havingcylinders 12, in which can be displaced simultaneously two slidingpistons 13, firmly connected together behind by a cross-piece I 19 andsupporting in front the compressionroller 14, which may in this mannerbe adjusted horizontally when ,the said pistons are operated by means ofthe lever l5, pivoted at 16' upon the cross-bar 17 and connected to thepiece 19 by the rod 18. The dippingroller 9 is of a diameter suicient toinsure that the surface of contact with the hank 10 will suffice tocause said hank to revolve. The roller 9 is journaled in two supports,of which the one, 6, of larger dimensions, is fixed and forms part ofthe frame lla, whereas the other support, 7, forms part of a mechanismpivoted laterally at the point 8 upon the frame llb and permits thecorresponding end of the said roller to be completely liberated by themovement of the piece 7 by means` of the han- IOO dle 33 for the purposeof inserting or withl drawing the bank of yarn IO at the commencement orthe end, respectively, of each operation.

Upon the front of the frame carrying the machine is mounted a transverseshaft 25, revolving in two bea-rings 24:, provided upon the frame. Thistransverse shaft 25 presents two extensions orarms 21, arrangedlaterally, and of which the end forms an open support 22, with a fork29, in which support rests each pivot of the stretching-roller 20, whichmay then be easily removed in order to be inserted in the hank l0. Acontrolling-lever 26, in one piece with the axle 25, enables theoperator to bring` the stretchingroller into the raised position, asindicated in dotted lines in Fig. l, while the catch 23, with its point27 sliding upon one of the supporting-arms 2l, will engage by its ownweight in the teeth of a semicircular ratchet-bar 2S, along which thesaid arm travels, and thus maintains the roller 20 in the positionrequired to effect the tension of the bank. (See Fig. I.) Thedipping-roller 9 is revolved in either direction, according as it may berequired to dip the bank or to express from it the excess of dye liquid.This is effected by means of a reversible gear mechanism 30,thedriving-shaft whereof is operated by manual or preferably by electric orother power, which permits of the mechanism being made absolutelyindependent and perfectly mobile along the whole length of the vat. Inthe case of electric driving the electric motor can be supplied by meansof a trolley receiving current from a conductor placed longitudinallyabove the vat.

The operation of the machine above described is as follows: Thepressure-roller 20 is first raised in the direction indicated by thearrow in Fig. l by means of the lever 26, and its axle automaticallyplaces itself in the hooks 20011 the supporting-arms 2l. One of the endsof this axle is then released from its hook, and the hank is passed uponthe roller, which is then replaced in its bearing and returned into theoperative position underneath the roller 9. 'lhe bank is then passedupon the dipping-roller 9, its axle having been released from themovable support '7 by turning this latter in the direction of the arrowmarked on Fig. 2, the removable bearing 3l having been taken away. Afterthe replacing of the axle inthe support 7 the said roller 9 is set inmotion by means of the bevel-wheel gearing 30 in the desired directionand causes the hank to move, which then passes through the bath acertain number of times until the threads thereof are fully charged ordyed. The rolier 2O is then again raised in order to lift the bank ontof the bath and to eifect the tension of the said bank, while thepressureroller la is caused to approach the roller 9 by means of thelever l5, which is pressed in any convenient manner to effect theneedful pressure upon the hank. By aid of the revel-sible gearing 30 theroller 9 is caused to travel in the direction opposite to that for thedipping of the han k,which is then compressed while under tensionbetween the aforesaid rollers 9 and 14, which has lfor its result thepressing out of the excess of dye which has been taken up. The coloringliquid is thus expressed Without the need of twisting the bank-that isto say, without disturbing the threads-as would have been the casein theoperation by hand. In order to obtain a regular color over all thehanks, it is obviously requisite that the duration of the dipping shouldbe always the same at each dip-that is to say, that the roller 9 shouldeffect the same number of revolutions. For this purpose the machine isprovided with an indicating device having a dial, (not illustrated inthe drawings,) and by looking at this the operator who has charge of themachine can stop the dipping at the required moment. The same indicatoralso serves to indicate the amount of wringing of the dipped bank. Afterthe complete passage of all the hanks through the flrst dye-bath themachine is caused to travel to the second bath, and the banks are thenagain dipped in the same order and subjected to the same treatment asbefore, the operation being repeated in the subsequent baths until thedesired color is obtained.

It will be obvious that my invention is not limited to the precisearrangement of parts illustrated in the drawings and that I may makedetail modifications in the different 0rgans or mechanisms which composethe machine within the limits of the principle of the system set forth.For instance, the compression-roller might be arranged to operatevertically or by describing an are of acircle instead of travelinghorizontally. In like manner the removal of the stretching-roller mightbe obtained by horizontal displacement, &c.
